Seemed a little funny to me too, so I checked the model #, and also called them for clarification. The "Forest Green" ones are indeed the SLCnew, and the black ones are the old style. I bought and received the SLCnew, love 'em. I used to have I believe a 8x30 SLC MkII (mid 80's?), these new ones do seem better in every respect. In fact, they seem every bit as good as my Ultravid 8x32's.
